Purpose:
Some pre-1/8/2004 long wheel base Toyota Coaster PLB have their original seats
rearranged to create space for luggage racks. Their seat belts might have been removed
by the owner or his agent.

Vehicle Models Approved:
Toyota Coaster BB50R-ZCMSZ.
3.
Seat Model Approved:
The seats must be supplied by the original vehicle manufacturer (Toyota) for the vehicle
model with original integral/retractable lap belts.
4.
Approved Design and Installation Details:
The Approved Design and Installation Details are shown in Appendix 4. The
installation method and parts used should be strictly adhered to the specification
stipulated in the Appendix.
5.
Before Retrofitting:
The condition of a vehicle affects the strength of its body frame structure. As such, a
PLB vehicle should meet the criteria as set out in Appendix 5 before retrofitting work is
to proceed. Vehicle conditions that do not meet the criteria should be repaired, and
vehicle parts not up to the standard should be renewed. TD request that a PLB vehicle
should be examined by a Registered Professional Engineer (RPE), in Mechanical or
Structural discipline to ascertain that its body condition shall meet the criteria, before
retrofitting work is to proceed.
6.
Certificate from Registered Professional Engineer:
During the process of retrofitting, the vehicle has to be examined by the RPE at key
stages and on completion. He should certify that the retrofitting is completed in full
accordance with the Approved Design and Installation Details.
Particular attention is
drawn to the proper functioning of locking mechanism of the seat belts. Normally
he/she will take photos for records with registration marks on hidden parts, and shall
make identifications such as paint dots on essential positions to assure that they are
properly located and tightened. The form of certification is shown at Appendix 6.

Approval of Notifiable Alteration from TD
With the RPE’s certification in hand, the owner (or his agent) may write to TD applying
for notifiable alteration of his vehicle. TD shall then arrange a date and time for
examination of the vehicle, and shall issue an approval letter if deemed fit.
8.
Vehicle Maintenance
It is essential that an altered vehicle, once approved for alteration, shall be kept in the
condition as approved in its subsequent operation. Damaged parts shall be replaced or
repaired to restore vehicle safety standards and roadworthiness. Without further
approval from TD, the vehicle shall not be further altered, or reinstated to its original
condition before retrofitting, for any individual components or for the whole vehicle.
